I am a starting researcher at Inria Saclay in the CEDAR team and part-time assistant professor at École polytechnique. I am also in involved in LabIA, a government initiative to bring the benefits of artificial intelligence to public administrations. Previously, I was a postdoctoral researcher at Max Planck Institute for Informatics in the team of Gerhard Weikum. I received my Ph.D. from Télécom Paris University and my advisor was Mauro Sozio.

My research interests are in natural language processing, graph mining, and computational social science.

Originally I am from Romania and more exactly Rucăr, a village in the Carpathian Mountains.
